The sunroof mechanism, and the repair to ask for before the quotemajor
Separate from the glass, the mechanism fails. The wind deflector — the air dam that lifts at the front when the roof opens — snaps off and jams or wrecks the track. "Sunroof is stuck in an open position unable to be closed. Upon attempting to open the sunroof, the deflector snapped off the assembly and the sunroof track broke." The bills that follow are the point: "The only fix according to the dealer was to replace the entire unit which cost more than $5k with parts and labor." "The dealership indicated the sunroof is beyond repair and requires installation of an entirely brand new sunroof assembly at a cost of $5,730 because it occurred outside the warranty (warranty expired at 60,000 miles and the car had 70,463 miles when sunroof broke)." One owner was quoted "close to $400 JUST to find the problem", found the broken deflector himself in ten minutes, and priced the parts at "close to $4,000! Without labor!!" Kia has a bulletin for this covering 2019 to 2022 Tellurides built between 15 February 2019 and 19 January 2022, instructing dealers to perform "a partial replacement of the sunroof wind deflector and mechanism arms" where "the sunroof open/close operation [is] inoperative and/or the sunroof wind deflector function [is] inoperative". That is a parts-level repair. It is worth asking for by description before any assembly is quoted.
